This guide takes you from a finished Sellrn storefront to a built mobile app ready for App Store and Google Play submission.

Prerequisites

Node.js 18+ installed on your computer.
Expo CLI installed (npm install -g expo-cli).
An Apple Developer account (for iOS, $99/year).
A Google Play Developer account (for Android, $25 one-time).
Your Sellrn storefront has at least one published page with universal bricks.

Step 1 — Generate the Mobile Manifest

Go to Dashboard → Mobile app.
Review the Coverage report. Aim for at least 80% universal brick coverage before exporting.
Click Generate manifest. Sellrn compiles your pages into the Mobile Manifest JSON and publishes it to a URL.
Copy the Manifest URL — you will need it in the next step.

Step 2 — Set up the Expo starter

Clone the Sellrn Expo starter from GitHub: git clone https://github.com/sellrn/expo-starter.git
Install dependencies: cd expo-starter && npm install
Copy the example environment file: cp .env.example .env

Open .env and set:

EXPO_PUBLIC_MANIFEST_URL=https://your-manifest-url
EXPO_PUBLIC_STORE_SLUG=your-store-slug

Step 3 — Run in development

Start the Expo development server: npx expo start

Scan the QR code with the Expo Go app on your phone to preview the app live. Changes to your Sellrn store are reflected after you re-generate the manifest.

Step 4 — Configure app identity

Edit app.json in the Expo starter to set your app's identity:

Field	Example
`name`	"Atem Goods"
`slug`	"atem-goods"
`ios.bundleIdentifier`	"com.atemgoods.app"
`android.package`	"com.atemgoods.app"
`icon`	Path to your 1024×1024 app icon PNG.

Step 5 — Build with EAS

Sellrn uses Expo Application Services (EAS) for building. Install EAS CLI and log in:

npm install -g eas-cli
eas login

Build for both platforms:

eas build --platform ios
eas build --platform android

EAS builds in the cloud — no Xcode or Android Studio required on your machine.

Step 6 — Submit to stores

eas submit --platform ios
eas submit --platform android

EAS Submit uploads your build to App Store Connect and Google Play Console. Review times are typically 1–3 days for Apple, and a few hours for Google Play.

Updating the app

When you update your Sellrn storefront, re-generate the manifest from Dashboard → Mobile app. The app fetches the latest manifest on next launch — no app store re-submission required for content changes.

For code changes (new features, UI updates), build and submit a new app version via EAS.
